It is a different world we live in.
A "Me Too" world.
There was a time when I'd walk up to a guy at a hot rod gathering and ask the owner of a car about the "build" and he would know everything about it...because he had either done it himself or with a couple of pals.
Now, you see a lot of cars "built" out of a catalog.
The same parts are on most cars, the same billet, etc.
Walk up to a guy at a rod run and ask what steering box he is running today and dds are he won't know.
Same deal in the UTV world.
The aftermarket support is unreal, but the number of guys who are building their own rides is pretty small. It doesn't bother me unless I hear some clown saying he actually fabbed something that I know he got outta some catalog or off the 'net.
I have the welders, the lathe, the mill in my shop. It doesn't take long to ID the pretenders.
Sitting down with a credit card and ordering a bunch of whiz-bang bling does not a builder make.
Does it bother me when people use the term?
Not really. Most people don't know what they don't know...so ya just gotta smile, and ignore 'em. The world is full of pretenders.
